The Shrine of Miosach (also known as The Misach, Irish: Míosach) is an elaborately ornamented 11th-century Irish cumdach (book shrine). It originates from Clonmany, north County Donegal, and is first mentioned in the 1165 Irish annals. It is dated to the late 11th century, when it probably contained a manuscript with psalms or extracts from a Gospel. However, the shrine was empty when first described in detail in the 18th century. It was originally associated with St Cairneach, patron saint of Dulane, County Meath, but by the late medieval period had become part of the cult of the abbot and missionary Colm Cille (521-59 AD).
